New rig won't talk to monitor

Hi everyone

My brother and I are building a computer for our parents. We had everything set up fine, to the point that we had installed Windows. We went back inside the case to do cable organization, and when we were finished, we tried to turn the computer on again, and the GPU wouldn't communicate with the monitor - because we had forgotten to plug the GPU back in (we unplugged it because it was in the way of some cables). So we plugged it back in, and all the LEDs and fans (including the GPU fan) and such inside the case were humming along fine, but the GPU would not talk to the monitor at all. We've reconnected the monitor umpteen times, reconnected the GPU to the power supply, and all those things, and nothing seems to work. We don't have another monitor handy to test if that's the problem (the monitor is turned on and displays its standard "no input" message even when plugged into the GPU.)

Any ideas? If we can find a second monitor to try we'll do that, but we're stumped for now.

Thanks a lot!

Hi Zhankfor :D
Things you can try include 1: Try connecting the monitor to a laptops VGA port, this will confirm whether the monitor and display cable are ok (check the cables condition, check connectors for bent pins and they are secure at both ends) 2: Try removing and re-seating both the Ram and graphics card again 3: Clear the CMOS to restore the MBs factory default settings, to do this remove the silver CR2032 battery from the MB for a few moments and then replace it, if you get the screen back you will need to go into the BIOS and reset the time and date, save the new settings and exit.
